TIRE-MAKING' intentan.

T all Iwhom 'it may concern.'

Be it. known' that I, WILLIAM B'. HARSEL,

a citizen of the 4United States, residing at Akron, in the county of Summit and State IS of Ohio, have invented certain new and useful linprovementsin Tire-Makin Machines,

of which thefollowing is a specification, reff erence being had therein to the accom panyin drawing.l s fi his invention relates broadly to tire makingmachines, it has more especial reference to ii'iai'ihinesl for "forming` carcasses (socalled)` of`ipneuniatic tires and it includes certain novel instrumentalities for effecting 15 predetermined and accurate movements of y certain. "Cif the operating` parts, whereby the.

machine' is, in a large measure, rendered automatic... One of the Aobjects ofthe invention is to provid.v (in connection with the pressuresuppprlgng carriagefot the machine) fa single l'actiiatmggmeans for effecting b oth an :idvanci f movement and a` recedingr movement, ieof". in relation to a tire-form or gg core` upto -iich the carcass is formi-al.

' object'of the invention is to pro- 'i reiiiinectionf with the aforementioned vide (i1 e p actua .j means.) mechanism for automate., cally the `carriage at a predeterrelation to the core, whereby "ay opera-tein siiehmanner as asinininium any manual operi VAliillyare necessarl to be made operating ot er types of farmf riparare it iaaiafter the earring@ A arrested by;

the operation thereof being effected automatically and in predete'mmed relation of the carriage `lto the core.

A further specific object of the invention,

in another aspect thereof, is to provide a machine 1n which the single fluid-operated means is controlled by the carriage itself when the same shall have reached a predeter-` mined position with i'espect'to the core,-

ivhcreby the carriage may be arrested Vand then, by the fluidi ;perated means, returned to startin position.

Other important ob] are inherent in the structure and will be=ol` rions from the appended drawings ill-lst .a-

ccts and advantages tive thereof, while the following specitieal tion [will make clear other,objects and .-|..l vantages of tlie sa me.

yl am aware' that it effect a feediiig movement of a presser-suppoi'tilmY carriage toward a tire-form by pneu-` matic means; but I believe it to be entirely novel with as to providea single fluid-oper- .is not broadly new tol ated mechanism for effecting` the receding-as well as advancingmovement ofthe carriage,- a'nd to combine therewithnieans for-arresting `thecarriage automatically at a predeterjwhereby the Huid-operated mechanism w-ill temporarily be givena reverse movement to. return the carriage to normal position. In

machines with which I am familiar thatlemploy pneumatic means for moving the caris' separate and dissimilar `from thepneumatic means is utilized to return the carriage i to starting-position. A structure which iii,-

nii-'ned stage' in its advancing movement i riage toward the tire-core, ymechanism that a bt a constructionV that involves several linstru-` mentalities which are entirely eliminatedfm i a machine constructed in accordance with?f my invention. The consequent economies and eflicieneies of my improved construction will, Ibelieve, be self-evident. l

' 'In order that the invention may readily` Vdraw-ings are'merely illustrative and that .the

be comprehended, IV have appended heretol'- `drawings which showv one embodiment there-l of; it being nnderstood,liowever, that these structure therein revealed is susceptible of a v wide range of modification and equivalencyff principles 4or C without departing fromthe spirit of the ,inventlolL l u these drawii'lgs:

Husa- In `the drawings, the referencecharacter 1 designates a base or pedestal upon which the operating parts of my invention are supported. Jutaposed to this pedestal and mounted in relation thereto in any suitable n nner, a tire-form or core 2, the same boing dis iesed for rotation at any required syv.eed. pon this core plies' of fabric are laid and Superposed to form the carcass, these plies being stretched and formed about the core by the 'forming mechanism now to be described'.

(7am-cass formi/ng mechafnism.-Mount-ed ,upon the base land adapted to have a, re-

ciprocating movement thereon in 'respect to the coi-e2 is a presser-supporting carrie 3.

Fabric-pressing members 4, arrange in spaced apart relation and adapted to move radially with respect to the axis of the core 2 and` to have a movement relatively to each other and independent of the travel of'the 40 carriage, are sustained by the carriage 3 through positioning members 45. Any appropriate means for actuating these mem? ers 5 may be employed such, for instance,

as those disclosed in a co-pending lapplication filed in. the joint names of, William B.

Harsel and Edward Nall, on the 3rd 4day 01. November, 1917, Serial No. 200,185, and which means, in this instance .preferably include pneumatic devices 5 or eecting "wmovemento f the pressing members rela-- tively to each other and independently of the traveling movement of the carriage',` all as disclosed in said application. As this ,particular means, per se, for-o erating the members 5 constitutes no part'o my present invention, a detail description' thereof is lnow deemed unnecessary.; It will suice to explain that these means are controlled in` such manner in respect to various stages of l) travel'of the carriage 3 that the pressingmembers 4 have. movements that are timed in relation to the position of the carriage in res ect to the core.v

Mage-actuating meckamsm.-To actuate lthe carriage toward and from` the core Aresrliect to the core.

2 in order to )osit'ion the pressingancmbcrs Jr and move tliem along the surface of the same radially with respect to its axis, il single power-operated means is provided and comprises the following structure: Mounted on the front end of the base l, and preferably below the plane ot' the carriage l is a supporting bracket ir which is dis'- posed a threaded member?" to which is movably connected an upstanding pistonsup port 8. By means of the threaded member T the support S may be adjusted in respect to the front face of the base l.

Carried by the support 8 is a piston 9 having a-piston-head l0 adapted to operate in a cylinder 11 into which fluid under pressure is to be introduced. Any appropriate pressure-fluid may be employed, and any suitable means for introducing it into the cylinder l1 may be utilized. As the strncture 'which 1 have `levised conlenulatrs the introduction ot' such Huid into the cylinder alternately at opposite sides ot the pistonhead 10, I have illustrated herein, as a pracltical means for supplying the fiuid to the cylinder 1.1,- a pipe lZ-which introduces the fluid into the rear end of the cylimlc1f-a.ml a pipe 13 which is adapted to introduce the fluid into its front end. vThe pipes 12 and 13 are joined in a valve-device 14, into which also extends a pipe 15 connected with a motor valvedevice 16 on a bracket 17, and" into which leads a supply-pipe 18, this, in turn, connecting With any suitable source of supply of fluid.Y underpressure. The valve.l

'Vhen the carriage has reached a predeterjA mined position and is arrested-inthe manV` l ner presently to' be explained .the Valve, deviceis automatically operated to cut olf the flow of fluid through the pipe 13, thev Huid then being permitted to pass through the pipe 1.2 into the rear end of the cylinder to effect a receding movement of the piston and, thus', of the carriage. In this way, and' by this single power-operated 4nieaz'is, their' carriage is caused to advance andI recede i its advancing movement so that it may be arrz'age 4 arres ingu mechanism. When the carriage' reaches a';predeter`rnined v posib tion in respect -tc the surface of the Acore---u and this is usually when thepressingsmem.-

1 automatically returned to starting position-z 11 and then "through the,

cylinder, w erebythe carnage is first stopped and then moved hack to starting the carriage, the latter,

seits cycle 'of operation, would position. To 4this end', the valve is provided Awith an actuating arm 20 fast on the stem 21. The pre'ssureffiuid, whichjs' admitted through the pipe into the valve 14 directed, according to the setting of the valve.14, either through the ipe 12 or the pipe 13. If directed througi the lat ter, the carriage is advanced; whereas, if directed through the pipe 1 2,l a receding movement of the carriage is effected. It is, thereforegdesirable to arrange for the setting of this valve automatically by lthe carriage, itself, so that the `carriage may control the valve. For this purpose, the lcar` riage carries 'two pins orposts 22 and 2 3, Fi s. 2, 3 and 6. Engagement of the arm, the in 22 throws' the valve to direct the uid tlirough` the pipe 135 whereas en-` agement of the arm by'th'epm 23 actuates t e valve to direct v the .pressure-Huid -through the'pipe 12. It will now be a parent that as the valve 14 is controlled y once havingbegun (unless con-v trolled` in some way) continue to advance r master valve-device 16 .the feed handle 26.4 Mounted At the Aextremityv ofV the structure i'eprovided:

and recede'because, .as soon as the .carriage has returned and the valve 14 is re-set to close the pipe 12 the pressure-fluid would be admitted to the pipe 13 and the carriage -would then be moved in theopposite direction. To control this action, however, the is provided so that of the pressure-fluid into thevalve 414 may be controlled' and the machine stopped-and started at the will of the opera,- f tor. The valvvel is manuallyl set by the operator, and for this purpose t e following A Fast on `a stem 2,4 of the valve 16 is an arm 25 provided `with a ongthe valve 16 is a second arm 21. arm 27 is pivoted a small 28,-.one arm of which is bellcrank lever provided with a,

lhook 29. adapted to engagea pendanty'pin' 30 on the arm 25 when the same shall have been movedbx'r the operator lto thedottedline sition indicated inFig" 7- lfro`xr"1"the -fulllme `position shown in th ame figure. The opposite end of the levelf28ilsl ada ted to engage withan abutmentfmember w `ich this instance, as an adjustable the carriage 3. .It will be understoodthat when .the operatorjsharll have moved the??V arm 25 to the dotted-line movements i sal on its pivot, whereupon the arm 25 is lposition, Fig. 7,

released and may then be swung by the operator to its fullslne position, which closes the master valve 16. As a result, the flow of pressurefiu d into the pipe 15 is shut olf so that no lu1d may then enter the valve 1.4.-A

Consequently, the carriage, beingthen at its operator opens .the valve 16 by swin ing the arm 25 to lts dotted-line position.

starting position, lremains` there 'until the,

mits the flow of 4pressure-fluid into the valve 14 so that such fluid may pass throu h-the.v

pipe 13 into the cylinder to initiate t e advancinq -movemerit of the "carriage, asf

already explained. While the valve 16 is o en, the valve 14 is o erative to'control t e advancing and rece ing movements of the carriage.

l. It will now be obvious that, in .m improved structure, a single Vmeans inclu in a? pressure-Huid'l mechanism, for actuating t e carriage for Lits,` advancin and receding res ect tot e. core, is pro-I vided; and, in ad ition, independent fllid- "pressure 'means are likewise provided actuating the fabric-pressers'4 in respectto 'the core butindependent of, the travel of the carriage.

Froml thefoiegoing, it will be perceived 'that I havedevised a simple'but very effective and .eicient structure, comprising comparativelyu few parts, and all constituting 'a single power-operated means, for ef fecti'ng the two\requ1red movements of the. carnage 1n 'respect to the core, combined' with means for automatically arresting the carriage in its travel.
